基于UG平台的油缸的参数化毕业设计.doc

摘 要 的CAD/CAM系统.通过UG的二次开发工具可以扩展UG 的功能实现某些特定产品的参数化设计和管理可以大大提高产品设计的效率 此次设计的题目是基于UG二次开发的油缸参数化设计管理总体思路是输入预荷油缸的原始设计参数通过相关公式及查表获得油缸的几何参数再通过油缸的几何参数建立油缸模型从而达到油缸参数化设计再通过对油缸的各个零部件的管理达到基于UG二次开发的油缸参数化管理 关键词： Abstract UG display the formidable function on CAD/CAM, but UG is the general support software system, only has the CAD/CAM basic function and not provide the complete computer-aided design/manufacture function which the special-purpose product needed. As a result of the ever-changing mechanical product,it needs to aim at the concrete object in the CAM software platform which selects to carry on the re-development and designs the nodding acquaintance good and it is easy to operate special-purpose product CAD/CAM system.Through the UG re-development tool,we may expand the function of UG and realize certain specific product parametrization design and the management.we also may enhance the efficiency of product design greatly. This design topic is based on the UG re-development on hydrocylinder parametrization design management.The overall train of thought is that we should input the primitive design variable of the pre-Dutch hydrocylinder,and obtains the geometry parameter of the cylinder through the correlation formula and the table, and then establish the hydrocylinder mode through geometry parameter of hydrocylinder , thus we achieve the hydrocylinder parametrization design and hydrocylinder parametrization management. Keywords: hydrocylinder,design parameter,geometry parameter, parametrization design,management目 录 摘 要 III Abstract IV 目 录 V 1 绪论 1 1.1 本课题的研究内容和意义 1 1.2国内外的发展概况 1 1.3本课题应达到的要求 2 2 相关软件 3 2.1 unigraphics NX的简介 3 2.1.1 unigraphics NX的概述 3 2.1.2 unigraphics NX的功能 3 2.2 Visual C++的简介 6 2.2.1 Visual C++的概述 6 2.2.2 Visual C++的功用 7 2.2.3 设计选用的原因 7 3 液压缸的介绍 9 3.1液压缸的分类和特点 9 3.1.1 活塞式液压缸［3］ 9 3.1.2 柱塞式液压缸 12 3.1.3 摆动液压缸 13 3.1.4 其他 14 4 预荷油缸的尺寸参数的确定 15 4.1 液压缸的主要尺寸 15 4.1.1活塞杆直径d 15 4.1.2液压缸内径D 15 4.2 液压缸的校核 16 4.2.1 缸体壁厚的校核 16 4.2.2 液压缸缸盖固定
